ABSTRACT Se presenta un estudio isotérmico de la precipitación de CaCO3 en un destilador solar experimental, utilizando como afluente agua subterránea con alto contenido de calcio, bicarbonatos y sulfatos solubles. Se efectuaron tres experimentos de la reacción entre el calcio con los iones bicarbonato. El primer experimento se siguió durante 5 h con el destilador libre de incrustaciones, el segundo, durante 12 h con incrustaciones y el tercer experimento por un periodo de 8 h con un tiempo previo de 72 h de contacto entre el precipitado y la solución. Durante las dos primeras horas en los tres experimentos precipitó 95.52, 145.37 y 444.44 mg de CaCO3, respectivamente. En el precipitado se encontró calcita como única fase cristalina.

    ABSTRACT: “Solar distillation” is a technology for producing potable water from brackish and underground water of low-quality at low cost. It can reduce water-scarcity problems together with other water purification technologies. Solar distillation is analogous to natural hydrological cycle. It uses an apparatus called a solar still in which water is evaporated using solar energy, a form of renewable energy, and collected as distillate after condensation of the vapor. It effectively produces distilled water after removal of impurities. The major advantage of this is the use of solar energy instead of electrical energy generated from conventional fuels. This helps in producing potable water without degrading our environment. Over time, researchers have studied several designs of solar stills to evaluate its performance for different climatic, operational, and design parameters. In this chapter, many aspects of this technology are being covered. Among those, the working principle explains the production of distilled water through evaporation and condensation process inside the solar still, including its advantages and drawbacks. The evolution of the solar still is discussed under the historical background section and classified as passive or active solar stills. Various heat gains and losses and a methodology to develop a thermal model to predict the solar still performance are presented. Thereafter, the effects of various parameters, economic, energy-exergy analysis including carbon credit, and technology transfer with challenges in adoption are given. In conclusion, the probable extensive use of this technology to solve water problems on a large scale all over the world is presented.

    ABSTRACT: PHREEQC version 2 is a computer program written in the C programming language that is designed to perform a wide variety of low-temperature aqueous geochemical calculations. PHREEQC is based on an ion-association aqueous model and has capabilities for (1) speciation and saturation-index calculations; (2) batch-reaction and one-dimensional (1D) transport calculations involving reversible reactions, which include aqueous, mineral, gas, solid-solution, surface-complexation, and ion-exchange equilibria, and irreversible reactions, which include specified mole transfers of reactants, kinetically controlled reactions, mixing of solutions, and temperature changes; and (3) inverse modeling, which finds sets of mineral and gas mole transfers that account for differences in composition between waters, within specified compositional uncertainty limits. New features in PHREEQC version 2 relative to version 1 include capabilities to simulate dispersion (or diffusion) and stagnant zones in 1D-transport calculations, to model kinetic reactions with user-defined rate expressions, to model the formation or dissolution of ideal, multicomponent or nonideal, binary solid solutions, to model fixed-volume gas phases in addition to fixed-pressure gas phases, to allow the number of surface or exchange sites to vary with the dissolution or precipitation of minerals or kinetic reactants, to include isotope mole balances in inverse modeling calculations, to automatically use multiple sets of convergence parameters, to print user-defined quantities to the primary output file and (or) to a file suitable for importation into a spreadsheet, and to define solution compositions in a format more compatible with spreadsheet programs. This report presents the equations that are the basis for chemical equilibrium, kinetic, transport, and inverse-modeling calculations in PHREEQC; describes the input for the program; and presents examples that demonstrate most of the program’s capabilities.

    ABSTRACT: An overview of desalination technologies is presented, focusing on those technologies appropriate for use in remote villages, and how they can be powered using renewable energy. Technologies are compared on the basis of capital cost, lifecycle cost, operations and maintenance complexity, and energy requirements. Conclusions on the appropriateness of different technologies are drawn, and recommendations for future research are given.
